Being around you in general is frustrating. You were the unserious twin; the one who found burning down buildings fun, skipping training when you two trained with Talia, sneaking food into your pockets, and now you found swinging your Violin bow and sword around fun too.
While Damian was the opposite, it did amuse him occasionally how idiotic his biological sibling could be.
You two were in a random part of the Wayne Manor, and he watched you off on the side while you talked to yourself, and him too.
For entertainment purposes, you got one of your favorite swords which you stole from your guy's mother, Talia, and the same bow you used to play Violin.
You were chatting with your brother distractedly, and swung the weapon around rather roughly while doing said action.
Until, you heard a particularly loud noise from right beside you; you turned your head, and realized you chopped off multiple blinds from the windows you were next to by accident.
You lowered the sword in shock, and your jaw went even lower. The most you ever did before was drop a bit of juice, and now you sliced off multiple blinds in the span of two seconds.
Damian's eyes widened about a centimeter, before he rolled them. Of course he rolled his eyes, "Idiot. How could you swing that badly and hit the blinds instead?"
He scoffed, and you wondered just how the hell you would cover this up.
